• The communication server activates PARE or CD at the public network provider.
• The network provider takes charge of the Call Forwarding Unconditional; the 2 B
channels are freed.
• User C is called. He is presented with user A's phone number and the redirecting in-
formation by way of CLIP. At the same time the redirecting information is also trans-
mitted back to user A (see "Display for Call Forwarding Unconditional", page 84).
Call charges:
• User A pays the call charges up to the call forwarding location on the network.
• User B pays the call charges from the call forwarding location to user C.
Call Forwarding Functions Supported
The system routes the following call forwarding to the exchange:
• Call Forwarding Unconditional (CFU)
• Call Forwarding Busy (CFB)
• Call Forwarding on No Reply (CFNR)
• Call Deflection (CD) by a user (forwarding a call during the ringing phase)
With all call forwarding functions the call only continues ringing at user C once it has
been forwarded to the exchange.

• ISDN network interfaces BRI-T/PRI (QSIG and analogue are not supported).
• In point-to-point operation the supplementary service partial rerouting must be avail-
able (subscription may be required).
• In point-to-multipoint operation the supplementary service call deflection must be
available (subscription may be required).
• User B must be defined as a User-type individual destination in the call distribution
element used by user A to make his call.
• The relevant authorizations must be enabled.
• If the call number of the external call forwarding destination is entered as an
analysable digit sequence in an LCR table and LCR is activated, the parameter
Partial rerouting (PARE) for LCR
